Inside this issue Animated chemical pathology Role of Chemical Pathology in Screening and Diagnosis of Multiple Myeloma Harmonization- A global effort to improve patient care Meta-analysis Accreditation of clinical laboratories Changing Role of Laboratory Medicine December 2014 THE SPECTRUM From The Editor`s Desk Third issue of The Spectrum is in your hands. In this issue we are lucky to have assistance from Dr Maryam Rafiq who has joined the editorial staff this year. She is the same Dr Maryam who won the title of Chemical Pathology Laureate in DLP-2. Her brilliance in literature and IT skills was recognized by Dr. Sara Reza who recommended her name for sub-editorship. We are also greatly indebted to Dr Sara Reza herself for sparing precious time, so close to her final examination, for this issue. We dedicate this issue to Prof (Brig) Dilshad Ahmed Khan, President PSCP, who has just retired from Army service. Once again the newsletter owes its success to the con tributions from our young colleagues. Their brilliant and creative ideas were translated into some very interesting printed matter. For example, the survey appeared in this issue is a masterpiece from our two sub-editors. Some very informative articles on ‘Lab Accreditation’, ‘Role of Lab Medicine’, ‘Warburg Effect’ and ‘Harmonization’ are useful contributions in the issue. We are honoured to include an Islamic article in this issue and beautiful poem on Youth is the first piece of poetry in the newsletter. Please go through the article ‘What is in the name’ and give Your opinion as requested at the end. ‘Brief report on DLP2’ is included to archive this important educational activity while ‘Animated Chemical Pathology’ is probably the first of its kind in any Pathology literature. I hope you will find the issue not only entertaining but also a source of some useful information. Lastly I want to pay my gratitude to Dr Qurat-ul-Ain, Dr Uzma Ansari and Dr Amina Tariq for helping in proof reading and all the people who have supported ‘The Spectrum’ morally and physically. Prof. (Brig) Aamir Ijaz email: [email protected] The Spectrum‘ and PSCP welcome participants of 3rd Joint Conference of the Societies of Pathology and 7thNational Conference of PSCP from 19th to 21st Dec 2014 at Khyber Medical College, Peshawar The PSCP sessions will be: Two Pre-Conference Workshops: Research Designs in Diagnostic Studies – 18th December 2014 (Thursday) from 0900 h to 1300 h. Interpretation of ABG Reports – 18th December 2014 (Thursday) from 1400 h to 1800 h. Plenary Session comprising talks by senior Chemical Pathologist on 19th December 2014 (Friday) Four Scientific Sessions of free papers of Chemical Pathology December 2014 THE SPECTRUM Second Edition of Distance Learning Programme in Chemical Pathology (DLP-2)-Brief Report During the feedback of DLP-1, many participants demanded that DLP should be continued in 2014, so DLP-2 was started on 19 Jan 2014. The topics were selected after proper consultation with senior Chemical Pathologists. Some of the seniors also prepared some lessons and DLP2 is deeply indebted to them i.e. Prof Dilshad Ahmed Khan, Dr Muhammad Aamir, Dr Naveed Asif and Dr Zujaja Hina Haroon (AFIP Rwp), Prof Asma Shaukat and Dr Lubna Sarfraz (QAMC Bahawalpur), Dr Ayesha Habib Khan and Dr Lena Jaffery (AKU Karachi) and, Dr Asma Naseer Cheema (AJK Medical College, Muzzafarabad). A schedule of the lessons with dates was sent to the participants and lessons were sent on alternate Sundays without fail (Alhamdolillah).The number of participants was quite higher as compared to DLP-1 and participants` response was also much more enthusiastic. DLP-2 consisted of 20 lessons and was participated by 78 trainees and 23 consultants out of total 113 registered participants. Lessons were made in a uniform pattern with 10-12 days for response. The students also contributed in the key presentations and developed an increasing sense of participation Category: Distant Students in the programme. Although in some lessons trainees of AFIP (near students) were allocated topics to prepare slides, generally participants sent slides voluntarily. In this regard, contribution from Dr Sabiha Waseem (Canada) is really commendable. Skype sessions followed each lesson and the number of sessions ranged from one to three to facilitate the participants. Connectivity remained an issue in the Skype sessions but participants never got frustrated indicating their deeply entrenched interest in the process of learning. Facebook page of PSCP was also extensively used for sharing literature and important announcements. Dr Usman Munir, a very efficient administrator of the group, changed the cover picture according to the running lesson and kept the group alive. At the end of programme, nine top positions in three different categories were announced based on the total scores earned. In addition, CME/CPD credits have also been awarded to the participants at the rate of 5 credit points per lesson. Facilitators who developed the lessons were given double credit points i.e. 10 per lesson. Top position winners of DLP-2 are: Category: Near Students (AFIP Rwp) Category: Junior Consultants Chemical Pathology Laureate: Dr. Maryam Rafiq, QAMC Bahawalpur 1st Position: Dr Qurat-ul-Ain 1st Position: Dr Sajida Shaheen, PNS RAHAT Karachi 2nd Position:Dr Farheen Aslam, QAMC Bahawalpur 2nd Position: Dr Uzma Ansari 2nd Position: Dr Muhammad Anwar Jatt, CMH Quetta 3rd Position: Dr Sara Reza, QAMC Bahawalpur 3rd Position: 3rd Position: Dr Saleha Zafar, QAMC Bahawalpur Dr Amina Tariq 5 December 2014 THE SPECTRUM Animated chemical pathology Here is a very unique way of presenting scientific concepts. We have given life to our favourite substances and molecules. It may help to remember these ideas besides entertainment AST –The CheAter: Heart expelled AST saying “go away cheater -you are also loyal to the liver” (AST has been removed from the list of cardiac markers because of its nonspecificity). To add to its insult liver also gives preference to ALT on AST because of its relation with heart. So poor AST is out of heart and liver, on the accusation of cheating. Do we have a lesson here to learn? HDL and CETP –The Hero and The Traitor: ‗H‘ for hero and ‗H‘ for HDL, our hero has a lot of potentials and plays multiple roles – just like Hercules again with an ‗H‘. He has a lot of enemies to fight with alone e.g. LDL, VLDL, IDL and Lipoprotein (a). He very successfully fights but unfortunately there is also a traitor in his army and it is Cholesterol Ester Transfer Protein (CETP). When the hero (HDL) is taking cholesterol away from periphery to the liver, the traitor (CETP) smuggles some of its cholesterol to VLDL, which becomes a very dangerous particle i.e. small dense LDL (SDL). In return VLDL gives some cash (triglycerides) to CETP but this money (triglycerides) does not stay long with CETP and is taken up by the liver by the action of hepatic lipase. So at the end of the day the traitor is left with nothing and vanishes. Hepcidin – The Iron Master: Hepcidin, holding a stick in his hand, has been assigned the duty of controlling the porters of iron (Ferroportin). On a normal day (with normal Iron levels) the iron master is sleeping in his chamber and the porters keep on doing their job of transporting iron from inside the intestinal lumen to the enterocytes (besides other sites). When body has enough iron stock and does not require more iron from intestine, our iron master (hepcidin) gets a telephone call (from liver) to get up and stop his porters (ferroportin). He takes his stick and put all these porters in a cellar (internalization). In people with haemochromatosis, the iron master is off-stick and there is nobody to control the porters, with the result iron is continuously deposited in the body. TSH –The Worried Mother: A worried mother (TSH) brings her two sick children (T3 and T4) to the child specialist. Now whom should the doctor ask to get details? Mother of course, as children are too innocent to tell about their illness. So if you want to know something about thyroid disease (dysfunction) ask from mother (TSH) and not from the children (T3 and T4). The anxiety of mother cannot be compared with that of children. Do you agree? Fluoride -The RBC Controller : In a sample tube Sodium (or Potassium) fluoride addresses the RBCs “ Look gentlemen this glucose is not for you; so please don`t eat it. Its patient`s glucose and is sacred for us”. In the tubes without fluoride, there is nobody to control RBCs and they party with glucose as the main course!!

Please see the answers on page 10 December 2014 THE SPECTRUM TRIBUTE TO PROF DR. AAMIR IJAZ From Quaid-e-Azam Medical College Prof. Dr Aamir Ijaz , for us , he is one of the most exciting teachers we have come across in our academic career. We feel so grateful to have been taught by such a diligent and committed teacher, putting his heart and soul into teaching , driven by a constant need to give his best in contributing to the enlightenment of his students all over Pakistan. Sir Aamir Ijaz has a way of communi- cating with his students that resonated far beyond what most teachers ever manage achieve. Teaching is not just a job for him, it is a passion that flowed from his heart. Not only he is a great chemical pathologist but he also has a way of mak- ing us think critically, inspire us, and could make his lessons resonate within us , to even years afterward. His friendliness , constant motivation and impetus left an indelible mark in our educational journey . To put it briefly, this has made him loved, appreciated, and respected by the chemical pathology trainees all over Pakistan, especially the trainees from QAMC including me who has the privilege to learn from him over the past couple of years. We salute you Sir, these words can never be enough to laud your absolute dedication and impeccable allegiance towards your endeavor !!! Dr. Sara Khan 2nd year trainee, Chemical Pathology, QAMC, BWP Rosalind Franklin Rosalind Franklin, who was a scientist working in King`s College London, contributed greatly in the understanding of the structure of DNA. She came very close to solving the DNA structure between 1951 and 1953 but her crystallographic portraits of DNA were shown to James Watson without her knowledge. On seeing these pictures the solution became immediately apparent to Watson, and the results went into an article in „Nature‟ (one of the world`s biggest science journal). Franklin's work did appear as a supporting article in the same issue of the journal. Franklin died in 1958 of ovarian cancer probably due to over-exposure to X-Ray radiations. Nobel Prize in Chemistry was awarded to James Watson and Francis Crick, for their work in the discovery of the structure of DNA in 1962 four years I met an old lady, Her walk was slow but steady. She said, I was beautiful like you, My eyes shown like morning dew. My rose like cheeks, I used to climb the mountain peaks. I danced like a fountain flows, My hair with many glows. I was so engrossed, In my youth that I lost. I lost it in a split second, Without knowing it ever happened. Now I am so old That it is hard to keep the hold. My face covered with wrinkles, I no more see the star with twinkles. Time has passed like sand, Held in the closest fist of hand, Leaving behind just lines, on my face and no other sign. Leaving the memories good and the bad, Which I treasure with a smile but sad. I listened to her for a minute or two But had to take my own way too. Capt (Dr) Sumbal Nida 2nd Year Trainee (Chemical Path) AFIP Rwp December 2014 THE SPECTRUM Role of Chemical Pathology in Screening and Diagnosis of Multiple Myeloma Multiple myeloma (MM) is a cancer of plasma cells in the bone marrow. Normally, plasma cells produce antibodies and play a key role in immune function. However, uncontrolled growth of these cells leads to bone pain and fractures, anaemia, infections, and other complications. Criteria for diagnosis — the diagnosis of symptomatic multiple myeloma requires the following: M protein in the blood or urine, plus A bone marrow aspirate or biopsy showing that at least 10 percent of the cells are plasma cells or the presence of a plasma cell tumor (called a plasmacytoma), plus Evidence of damage to the body as a result of the plasma cell growth, such as high Calcium in the blood, Renal failure, Anaemia or destructive Bone lesions (CRAB) Screening Tests: Serum and Urine Protein Electrophoresis: Among the laboratory methods available for the separation of proteins, electrophoresis is a well-established and versatile technique widely used in clinical chemistry. Protein electrophoresis of serum and urine is a sensitive mean of detecting the abnormal monoclonal proteins found in myeloma. During electrophoresis, intact monoclonal immunoglobulin molecules will migrate as a sharply defined band called paraprotein. It is almost always found in association with Bence-Jones protein in the urine protein electrophoretogram. Quantification of non-isotypic immunoglobulins: Measuring total concentrations of IgG, IgA and IgM in serum can reveal elevation of a specific immunoglobulin isotype that is suggestive of the presence of a paraprotein. However, the test does not distinguish between the normal polyclonal and abnormal monoclonal forms of a particular immunoglobulin. Serum urea, creatinine, calcium & albumin: Many patients with myeloma have myeloma-related organ impairment (ROTI) in which corrected serum calcium of usually >0.25mmol/l above the upper limit of normal or >2.75mmol/l and serum creatinine of 1.9 mg/dl is suggestive of ROTI. Tests to Establish Diagnosis: Immunofixation electrophoresis (IFE) of serum and urine: Identification of the immunoglobulin isotype of a paraprotein by immunofixation of the paraprotein band enables it to be classified as an IgG, IgA or IgM molecule. The identity of the isotype is important in differentiating whether production of the paraprotein is by a clonal plasma cell disorder, or by a clonal lymphoproliferative condition. Tests to Estimate Tumor Burden and Prognosis: Quantification of monoclonal protein in serum and urine: Concentrations of serum paraproteins below the threshold value are more likely to be monoclonal gammopathy of uncertain significance and those above are more likely to be myeloma. ßeta-2 Microglobulin: Beta-2 microglobulin (B2M) is a useful tumor marker for some blood cell cancers, for detecting kidney damage, and for distinguishing between glomerular and tubular disorders of the kidney. As a tumor marker B2M test helps to determine the severity and spread (stage) of multiple myeloma and may sometimes be ordered to evaluate the effectiveness of treatment. 6 Dr. Noreen Sherazi, Agha Khan University, Karachi December 2014 THE SPECTRUM Alfred Nobel Alfred Nobel invented dynamite and made lot of money. In his will, Nobel directed that the bulk of his estate should be used to award prizes that would promote peace, friendship, and service to humanity. After his death in 1896, the governments of Sweden and Norway estab lished Nobel Prizes in five categories: chemistry, physics, physiology or medicine, literature, and peace. A sixth category, economics, was added in 1969. Every year, Nobel laureates as semble in Oslo or Stockholm on December 10th on the anniversary of Nobel's death. Each lau reate receives a medallion, a scroll, and all or part of a cash award currently valued at about $1 million per category. An Interesting Case Report A 64-year-old female presented with generalized fatigue, poor appetite, and weight loss. She had hepatosplenomegaly and diffuse petechiae. Her glucose was 1.4 mmol/L, HCO3 : 12 mmol/L, lactate: 28.5 mmol/L (Ref range, 0.5–3.4), and pH 7.24. Urine ketones were trace positive. She also had pancytopenia. Further workup for insulin-mediated hypoglycemia, growth hormone deficiency, adrenal insufficiency, and vitamin deficiencies were within normal limits. Bone marrow aspirate/ biopsy confirmed the presence of Epstein-Barr virus-positive diffuse large B-cell lymphoma of the elderly. Name the phenomena causing Hypoglycaemia in this patient and give its biochemical mechanism? 37th annual conference of PAP 2nd joint conference of societies of pathology Answer: Hyper-Warburgism. The extreme glucose consumption by the tumor and the paradoxical lactate generation by the tumor provide compelling evidence for an increased Warburg effect.

T oday‘s healthcare system revolves around evidence -based clinical guidelines that frequently rely upon laboratory test results to diagnose an ailment and to determine if and when treatment is necessary. This situation become more complicated by rapidly expanding use of EHR as well as an increasingly mobile population that results in use of different laboratories for same test at different times. Unfortunately, results of the same test from different laboratories often show large inter-laboratory variation and decisions based on these non-uniform test results increase the risk of erroneous clinical, financial, regulatory, or technical decisions that may have negative impact on patient care. There is wide agreement within the medical and laboratory community that harmonization of laboratory test results is critical to improve the quality and value of health care system. Harmonization of clinical laboratory results means that results between different clinical laboratory measurement procedures should be equivalent, within clinically meaningful limits, to enable optimal use of clinical guidelines for disease diagnosis and patient management. Harmonization of test results includes consideration of preanalytical, analytical, and post-analytical aspects. Breaking News Analytical considerations are the main focus of harmonization efforts by various organizations. The aim is to have the calibration of all procedures traceable to the same higher-level reference system and to have a common calibrator that is commutable with clinical samples for all of its measurement procedures. The conference of AACC recommended organizing a worldwide approach for prioritizing and managing the harmonization process. As a result International Consortium for Harmonization of Clinical Laboratory Results (ICHCLR) was formed to provide a systematic approach for prioritization of clinically important and technically feasible measurands to achieve harmonization and to formulate procedures for harmonization of measurands without any reference measurement procedure was likely to be developed. Post analytical aspects include harmonization of reporting units, referenced interval and decision limits. IFCC working group for reference intervals and decision limits is running a global project to assess potential for global reference intervals in various measurands. In Pakistan, AFIP is also a part of this multicenter study. Major (Dr) Qurat-Ul-Ain IV Year Trainee (Chemical Pathology) AFIP, Rawalpindi Structured Assessment of Skills (SAS) in Chemical Pathology Under the auspices of PSCP we have successfully conducted two DLPs for the improvement of cognitive domains of our students i.e. recall interpretation and application of knowledge. In the feedback of DLP2 many students demanded a programme of practical training. So we have decided to organize a skill training programme by the name of Structured Assessment of Skills (SAS) in Chem Path. This programme will focus on practical aspects including laboratory skills, data interpretation skills, lab and biosafety practices, managerial skills and soft skills (e.g. communication with patients, staff, clinical colleagues, administrators and venders, ethical issues and professionalism). The collective wisdom of all qualified Chemical Pathologists will result in development of a valid and reliable assessment format most suitable to our peculiar specialty. All the centers where MPhil and FCPS training in Chemical Pathology is conducted may participate in SAS and all consultants, supervisors and examiners in Chemical Pathology may participate in preparation and conduct of SAS. Chemical Pathologists who are presently not on a teaching appointment may contribute in making the questions. SAS will be conducted on monthly basis and it will comprise two components: Practical which will include „Major Biochemical Practical‟, ‗Quality Control Procedure‟ and TOACS. Data Interpretation Skills: Every month we may give a test of 10 cases. We will improve the format of this very essential component and give it a proper name. One suggested name is “Quick Assessment of Data Interpretation Skills –QADIS” 8 Further details of the programme will be communicated later.

Wish you a bright future filled with the promise of a wonderful career. 9 December 2014 THE SPECTRUM Meta Analysis Meta-analysis is a statistical procedure that integrates the results of several independent studies considered to be ―combinable.‖ Meta-analysis would be used for the following purposes: To establish statistical significance with studies that have conflicting results To develop a more correct estimate of effect magnitude To provide a more complex analysis of harms, safety data, and benefits To examine subgroups with individual numbers that are not statistically significant Conducting meta-analyses Location of studies: Meta-analysis requires a comprehensive search strategy which interrogates several electronic databases, hand searching of key journals and checking of the reference lists of papers. Quality assessment: Good meta-analyses will use objective criteria for inclusion or rejection of studies on quality grounds. Calculating effect sizes: Two approaches used are: odds ratio (previously), and now the risk ratio (relative risk). Ratio of 2 implies that the defined outcome happens about twice as often in the intervention group as in the control group. Advantages: To increase power To improve precision To settle controversies arising from apparently conflicting studies or to generate new hypotheses Considered as evidence-based resource Disadvantages: Difficult and time consuming to identify appropriate studies Not all studies provide adequate data for inclusion and analysis Requires advanced statistical techniques Heterogeneity of study populations Checking for publication bias : Examine a funnel plot. It displays the studies in a plot of effect size against sample size. Sensitivity analysis A good sensitivity analysis will explore effect of excluding various categories of studies. It may also examine how consistent the results are across various subgroups. Presenting the findings: Forest plot displays the findings from individual study as a blob or square, with squares towards the left side indicating the new treatment to be better, whereas those on the right indicate the new treatment is less effective. The size of the blob or square is proportional to the precision of the study. A horizontal line (usually the 95% confidence interval) is drawn around each of the studies‘ squares to represent the uncertainty of the estimate of the treatment effect. The aggregate effect size obtained by combining all studies is usually displayed as a diamond. Heterogeneity: A major concern about meta-analyses is the extent to which they mix studies that are different in kind. Studies can differ on the types of patient studied, the nature of local healthcare facilities, the intervention given and the primary endpoint (death, disease, disability). Meta-analyses should test for the existence of heterogeneity with 25% corresponding to low heterogeneity, 50% to moderate and 75% to high. If heterogeneity is absent, then the analysis employs fixedeffects modelling which assumes that variation seen between studies is by chance. Random-effects models assume that variation between studies exists. When the amount of heterogeneity is large, metaregression is introduced to overcome this problem . 10 Dr. Farheen Aslam 4th Year trainee, Chemical Pathology QAMC, Bahawalpur Answers of IQ test on page 4 Pour the second glass into the fifth glass. sptmbr Explanation:Name of the months after removing the vowels - APRIL, MAY, JUNE, JULY, AUGUST, SEPTEM December 2014 THE SPECTRUM Accreditation of Clinical Laboratories: Stride along the Perfection C linical laboratory results are central to diagnosis, risk assessment, management and monitoring of disease and accreditation is a formal, third party recognition of competence to perform specific tasks. Laboratory accreditation benefits laboratories by allowing them to determine whether they are performing their work correctly and to appropriate standards, and provides them with a benchmark for maintaining that competence. Laboratory accreditation is a voluntary activity of complete, accurate and objective assessment of laboratory processes and management practices. Accreditation helps laboratories demonstrate their efficiency, accuracy, and cost-effectiveness while keeping the main focus on quality and patient safety. Approved international standards are applicable and followed by approved accreditation bodies for medical or clinical laboratories accreditation. International organization of standard (ISO) has developed a laboratory standard for use only by medical laboratories i.e. 15189 (ISO 15189) which is a well-accepted international standard and specifies particular requirements for quality and competence of medical laboratories. Other medical laboratories standards are adopted from Clinical and Laboratory standard institute (CLSI), College of American Pathologist (CAP), The Joint Commission (TJC) and World Health Organization (WHO). International Laboratory Accreditation Cooperation (ILAC) is a global laboratory accreditation association. In conjunction with ILAC, specific regions have established their own accreditation co-operations such as Asia Pacific Laboratory Accreditation Cooperation (APLAC) for Asian and Pacific Rim laboratories. National accreditation councils and bodies are approved or affiliated with regional or international accreditation organizations to provide accreditation service to medical laboratories at national level. Pakistan National Accreditation Council is the statutory body, which have been assigned the task of accreditation of clinical laboratories in the country and it has already accredited a few laboratories. Medical laboratory accreditation bodies use standards to assess factors relevant to laboratory and quality management system. Usually a pre-assessment visit is scheduled before final assessment to highlight any area that requires attention with corrective action. At the end of final assessment a detailed report on evaluation is presented to laboratory to announce the decision about accreditation. On the basis of report if laboratory fulfils the minimum criteria for accreditation the laboratory is declared accredited and an accreditation certificate and number is issued to laboratory. Later surveillance is carried out to assess the maintenance of competence. Dr. Sahar Iqbal Consultant Chemical Pathologist Dow University of Health Sciences Karachi Workshop with Professor Ichihara (Japan) at AFIP, Rawalpindi 11 December 2014 THE SPECTRUM Changing Role of Laboratory Medicine C linical laboratories represent an area of healthcare that has always undergone major changes because of technological advances and external economic pressures. A hospital laboratory has to meet the requests for laboratory investigations by maintaining adequate diagnostic facilities, to provide professional advice on management of the patient, to provide laboratory facilities for research projects undertaken by clinicians, to collaborate in the development, study and control of new methods of treatment, to undertake applied research on pathology problems and to collaborate in education and training of medical and paramedical personnel. Pathology service plays a pivotal role in the disease diagnosis. With growing dependence on the laboratory services, more than two third diagnoses are made by the laboratory workup. These are the days of economical considerations and provision of cost effective services. It has been observed that at least, one third laboratory tests are solicited, without their relevance to the patient‘s care. If the efforts are made in the right direction, many highly sophisticated and costly tests may easily be replaced with a few simple and widely accepted tests. The laboratory-clinic interface is, therefore, of fundamental importance to ensure that the patient is given high quality care. In order to fill the need for better quality health care, avoidance of medical errors and cost reduction, three strategies have been recommended for supporting and promoting clinical consultancy in Laboratory Medicine. It is an era of Evidence-Based Laboratory Medicine (EBLM) which focuses on the use of diagnostic tests and the goal of improving patient outcomes. Asking a question is the first step of the evidence-based laboratory medicine (EBLM) cycle, the other steps being acquiring the evidence, critically appraising the evidence, applying the evidence and auditing use of the evidence. Whilst the main focus of the EBLM cycle is to provide a strong evidence base for use in clinical practice.

Please send your opinion at any of our emails. 5th PSCP CME course at AFIP, Rawalpindi 13 December 2014 THE SPECTRUM THE SPECTRUM SURVEY A s a Kid what did you want to be when you grew up? And how you ended up becoming a chemical pathologist? pathology so I decided to be a trainee of madam Asma, MASHALLAH a very co-operative and nice teacher. (Dr Kamran QAMC) I always wanted to be a doctor. During 1st year of MBBS I decided to do Mphil in anatomy as I observed the easy and relaxed life of anatomy teachers. But in 3rd year. I started making my mind for specialization in pathology. (I still re member the very first lecture of Pathology was taught by Prof Asma shaukat. When Ma‘am in troduced herself I was so inspired and told my friend, that one day I will be like her and now Alhumdulillah I am her trainee and I am proud of it. (Dr Nudrat Khan QAMC) My childhood dream was to become a nuclear scientist but I changed my mind just to fulfil the more prestigious wish of my mother to become a doctor. After joining army, I felt pathology, being an emergency free field, was the most suitable for me. In pathology I love chemical pathology because of its vast canvas and closeness to medicine. (Dr Qurat-Ul-Ain AFIP) As a kid I wanted to be a lawyer or justice but when I was not allowed to adopt the profession I took MBBS as second option which was wish of my parents as well. I chose chemical pathology for specialization because It is an interesting field and of course impressive personality of my supervisor made me join chemical pathology ( Dr shahnaz Noor QAMC) As a kid , it was my very " own " dream to become a doctor and I became a chemical pathologist by choice as well. On realizing the fact unlike other fields , there is still quite a lot of opportunity for females to excel in this emerging speciality. I then decided to take pathology part 1. (Dr Sara Khan QAMC) As a child, I always wanted to be a scientist. As I grew up, I chose to become a doctor as it was suggested by my parents. I chose Chemical Pathology because it is a vast and dynamic field which also touches other fields of science besides the medicine. ( Dr Masud Ansari QAMC) As a kid I had not as much defined goals, just had an inspiration to be a doctor. Ending up in chemical pathology was such a sudden decision of my life. I could not exactly figure out how I joined this field. May be I felt I can‘t cope with the hectic duties of medicine. I thought to opt a field in which there is an easy life style plus more chances to progress, as chemical pathology is relatively less saturated. (Dr Faghia Shahid QAMC) I wanted to become everything but a pathologist!! On a serious note I entered in the field of Pathology because of AFIP and in Chemical Pathology because of inspiration from Maj Gen Farooq Ahmad Khan (retd), my teacher and mentor. ( Prof Aamir Ijaz) I wanted to become doctor like my ideal mother .But I was inspired by my (late) father who was Professor of Chemistry, so the interest of being a doctor and Chemist turned out to be an amalgam—―chemical pathologist‖ (Asma Shaukat ) I wanted to be a doctor and fortunately was lucky enough (but off the record sara josh thanda par gya .it was a stressful time .UHS exams tu bas tension he tension thi). As I am a native of Bahawalpur and the only good option here is chemical 14 December 2014 THE SPECTRUM W hy Female doctors Opt chmemical Pathology more than male doctors?? ture so females opt Chemical Pathology more than male doctors. (Dr Ayesha Siddiqa QAMC) Because they get ample time and sufficient money to shop dopattas, angrakhas, choridaars and plas- mo? (What is the name of that very loose trouser? I am sorry I forgot) etc. ( Prof Aamir Ijaz) It goes very well with their family lives (Prof Asma Shaukat) The reason may be 3-fold; either the females are never scared of difficult things so they love to be in this challenging field or they are too innocent to understand the dire needs of this specialty or like , me they love the duty hours of this field. (Dr Qurat-Ul-Ain AFIP) Chemical Pathology is all about colors and I think females reflect the colored side of na- Yes it affects because LAURELS is more important than friendship!!! But hold on, there is another problem here. Some wise person once said ―the friendship which ended was, in-fact, never there” (Prof Aamir Ijaz) I think female doctors prefer the basic medical sciences over the clinical fields as they also have to look after their families. Chemical pathology has good scope and offers opportunities to progress for young pathologists. (Dr Masud Ansari QAMC) As females have a double job in their lives i.e. looking after their homes and kids and to excel in their carrier so chemical pathology is a field which provide you both opportunities (Dr Faghia Shahid QAMC) C ertainly, DLP improved our knowledge and had a vast impact on our understanding, did it affect your friendships?? DLP has created the atmosphere of competition among trainees and ironically it has created a lethal atmosphere of jealousy as well ....LOLz (Dr Nudrat Khan QAMC) DLP had an indirect impact on our friendships. It helped us to differentiate our real friends from the rest. ( Dr Masud Ansari QAMC) Yes, I am more friendly with my juniors ( Prof Asma Shaukat) Ahhmm! "kyun pakki dushmani karwani hai"… just kidding. Certainly not, rather DLP helped us in making more friends that was nearly impossible otherwise.Thanks to DLP we all are now a family. (Dr Qurat-Ul-Ain AFIP) No my friendships are all the same: D (Dr Sara Khan QAMC) Comfortable working environment makes them choose chemical pathology. Dr Sara Khan QAMC) Yes, it created an environment of competition among my friends so had a great effect on friendships.
